In previous builds of Sublime Text 3, if you opened a folder in Sublime Text, the sidebar would automatically be shown with the folder tree. Version 3.0 (3143) no longer has this behaviour, and instead mirrors the opened/closed state of the current window. Is there a preference that can enable the old behaviour?

The only options in that menu are "Show/Hide Side Bar" and "Show/Hide Open Files". I can show the sidebar manually with that menu or with a keyboard shortcut, but previously it would automatically show if I was opening a folder.

I have the same problem/question as the OP. But his solution doesn't work for me.

To be honest, I wasn't even aware about the old behavior the OP refereed to because I'm new to this program. But I was watching the tutorial video where they simply dragged the folder into ST and it automatically opened the side bar. In my case, it doesn't happen, so I always have to go with Ctrl+K, Ctrl+B to open it. The only relevant difference between my setup and the one form the tutorial that I can think of is that they were using Mac and I'm on PC. Could that be the factor here?

Also, the program is in a clean state. No single package has been installed so far.
